DUMP-CAR.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed October 13, 1906. Serial No. 338,840.

To all 'whom it may concern:

Be it known that we, HARRY S. HART and JOI-IN O. Nmkmx, citizens of the United States, residing at Chicago, in the county ot' Cook and State of Illinois, have invented. certa-in new and useful Improvements in Dump-Cars, of which the following is a specification.

Our invention relates to dump cars, especially to cars of the type known as the Hart convertible car; and has for its object to provide an improved car of this type in which provision is made for the e'fhcient and rapid unloading of the car and for dise tributing the load throughout the load sustaining members of the car.

In the accompanying drawings- Figure 1 is a longitudinal elevation, partly in section, of a car embodying our invention. Fig. 9. is a plan view of a portion of one end of our improved car. Fig. 3 is a plan view of a portion of our car, certain parts being removed to show the construction of theunderframe. Fig. 4 is a transverse sectional View on the line 4 of Fig. 1. Fig. 5 is a detail view of a part of the door operating mechanism. Fig. 6 is a modified form of the structure shown in Fig. 5.

In carrying out our invention we provide a car the underframe of which comprises bolsters a, intermediate cross members c and suitable longitudinal sills c2 connected to the holsters and to the cross members, as shown. Suitably secured to the holsters at each side of the ear are posts or stakes d shown in Figs. 1 and 3 as formed oi' channel beams and to these posts are connected the plate girder sides b, these plate girder sides having a lower longitudinal member 2) and an upper member 610 formed of channel iron. It will be observed that the lower member 5 of the plate girder side is supported a suitable distance above the floor level of the car. The plate girder sides are further supported by stakes cl of angle iron, these stakes extending downwardly below the level of the transverse members, as shown in Fig. 4, and the stakes Z are suitably connected to the transverse members of the underframe by gusset plates m, as shown in Fig. 4. Angle iron brace members ZX further serve to brace the plate girder sides, these members extending between the top and bottom longitudinal angle irons of the sides, The upper angle iron of the plate girder sides extends beyond the bolster to an upright ZJ hereinafter described.

The bottom of the car is shown as formed of hopper portions comprising a central hopper portion formed by the downwardly and inwardly extending plates e', c2 secured at their upper ends to the longitudinal members c2 of the under-frame, one of the plates c being secured to the longitudinal bar o extending the entire length of the central hopper portion. The other side of the central hopper portion is formed of a similar downwardly and inwardly extending plate e2 connected at its u per end to the longitudinal member c2 o the underframe, and by braces 7c to the opposite member of the central hopper portion. The central hopper is provided with doors g provided upon their under sides with braces It. The braces L extend above the upper' edges of t-he doors g and are hinged to brackets e secured to two longitudinal members c'. By this means the hinges lz, lie beneath the stationary hopper plate e2 where they are rotected from being clogged by the la ing transported in the car. Suitable hopper portions are also formed at each side of the central hopper portion by downwardly and outwardly extending plates e and e8 attached at their upper ends to the longitudinal members c2 of the underlrame and at their lower ends to the lower ends of the stakes Zmclearly shown in Fig. 4. Suitably hinged, as at f to the sides of the car, are doors so hinged as to swing outwardly when released. It will be observed that the upper member L10 of the plate girder side extends beyond the end oitl the supporting post d and has connected to its outer end a support this support b being in turn connected to a short side sill "D20 extending from the bolstertoward the end of the ear, and the end sill c3 is in turn connected to the short side sills. It will be seen that the end sills are carried or hung from the extension of the side plate girders. Suitable draft beams o* are connected to the end sill and to the bolster, as will be readily understood.

It will thus be seen that we have provided a car with hopper portions and doors so arranged as to deposit the load of the car at the sides or at the center, or both, as may be desired.

By supporting the plate girder sides above the floor level of the car, it will be seen that we provide a suitable space between the lower member of the sides and the floor of the car. We thus provide a wide opening through which the material maybe dumped from either side of the car, as will be readily understood from an inspection of Fig. a. We also provide a car having high sides, which serve to retain the load efficiently and transmit this load to the bolsters by which it is ultimately carried.

In order to operate the side doors, we provide rthe following mechanism: finding shafts f2 are arranged longitudinally of the car and extend through the end sills, where they are provided with any suitable operating device f8. We also provide what we term a drop shaft f3 mounted in suitable inclined guides m. The drop shaft f? is connected by a chain f4 to the winding shaft, and the chain f5 passes around the drop shaft and is secured at its ends to the hopper bottom and to the side door, respectively, the connection to the door being shown at f7 and to the hopper bottom at f, By unwinding the chain f"c the drop shaft is allowed to travel downwardly in its guides, thus permitting the door to open, and it will be observed that as the chain connected to the winding shaft is unwound twice the length of the chain, which is co-nnected to the door, will be released, thus permitting the door to open to that increased extent.

It will be readily understood that the winding shaft and its connection to the drop shaft may be omitted and the drop shaft operated directly by any suitable means. For example, the shaft may be provided with pinions engaging racks upon the guides, as clearly indicated in Fig. 6, the shaft in this instance being, of course, provided with a suitable operating means at its ends.

In order to operate the central door g, we show a winding shaft g mounted in suitable .bearings g2 in the underframe of the car and connected by the chain g3 to the door, the connection being shown at g4. b represents the inclined ends of the car and b2 the inclined ends of the hopper bottom, the ends of the car being suitably supported by upper and lower transverse braceV members b3 and b4, respectively, the upper brace member being supported from the sides of the car and suitably' braced by an upright 66. The

Vlower portion of the end of the caris secured to a transverse member b4, which also -serves to support the upperportion of the end of the hopper. Transverse braces b5 and inclined braces 57 serve to further strengthen the ends of the car. Suitable metallic pieces bg, which may be of angle bar-as shownserve Yas supports for the sides of the car ends, as will be readily understood.

It will be seen that we have provided an all-metal ballastbr dump car, providing therein means for dumping the load from the hopper bottom either at the sides or the center of the car in which the loadis carried by the plate girder sides and the bolsters.
